A turnkey solution is a type of system that is built end-to-end for a customer and is designed to fulfill a certain process such as manufacturing, billing, website design, training, or content management. It is immediately ready to use upon implementation and is different from a custom-built or designed system. The term "turnkey" refers to the fact that the customer, upon receiving the product, just needs to turn the ignition key to make it operational, or that the key just needs to be turned over to the customer. Turnkey solutions are "off the shelf" solutions or "ready-made" solutions that can be easily deployed in a business, effectively needing the end-user to simply "turn the key" to get started.

Pros of turnkey solutions include that they are cost-effective, easy to implement, and can be quickly deployed. They are also designed to be appropriate for most types of businesses and organizations, making them best suited for those businesses who have just started their digital transformation journeys. However, turnkey solutions can lack the customization and integration necessary for businesses today, particularly those for whom flexibility and scalability are important. They are not suitable for businesses with major customization requirements.

In summary, a turnkey solution is a lightweight digital strategy to gain the functionality a business needs quickly and in a cost-effective manner. It is an all-in-one product or service thats ready to use as soon as you buy it.
